How do the two graphs compare if the frequency factor of the second reaction is higher than the frequency factor of the first reaction but the two reactions have the same activation energy?
a The lines will have the same negative slope, and the y-intercept of line 2 will be higher than the y-intercept of line 1.
b The lines will have the same y-intercept, negative slope direction, and the slope of line 1 will be steeper than the slope of line 2.
c The lines will have the same y-intercept, negative slope direction, and the slope of line 2 will be steeper than the slope of line 1.
d The lines will have the same negative slope, and the y-intercept of line 1 will be higher than the y-intercept of line 2.
Explain why higher levels of defects are found in solids at high temperatures and close to their melting points.
If the O2 gas present in 7.30 L at STP is changed to a temperature of 17 degrees Celsius and a pressure of 788 Torr, what will be the new volume?
Consider a binary liquid mixture A and B, where A is volatile and B is nonvolatile. The composition of the solution in terms of mole fraction is xA = 0.045 and xB = 0.955
Use the systematic treatment of equilibrium to determine the pH and concentrations of species in 1.00 L of solution contatining 0.070 lysine HL 0.055 mol aspartic acid H2A and 0.0080 mol NaOH.
Draw all resonance structures for anisole to show why the methoxy group directs incoming electrophiles
A cylinder of compressed gas rolls off a boat and falls to the bottom of a lake. Eventually it rusts and the gas bubbles to the surface. A chemist collects a sample of the gas with the idea of trying to identify the gas.
One liter of a buffer solution is prepared by dissolving 0.150 mol of NaNO2 and 0.070 mol of HCl in water. What is the pH of this solution? If the solution is diluted two fold with water, what is the pH?
what is the energy of a single UV photon and a mole of UV photons having a wavelength of 25 nm?
An appropriate indicator is used. Ka for acetic acid is 1.7x10^-5. Calculate the pH in the flask after 300 mL of 0.100 M NaOH has been added
Oxygen and sulfur combine to form a variety of differenet sulfur oxides. Some are stable molecules and some, including S2O2 and S2O3, decompose when they are heated
Imagine that 1.00 mol H2O(l) is placed in a piston with a constant external pressure Pext = 1 bar. The piston is then placed in a large thermal bath at a temperature of 270 K.
You titrate a 0.1000 M solution of a strong base (NaOH) with a 100.00 mL solution of 0.1000 M Formic acid (Ka = 1.80 x 10^-4). Calculate the pH at the following points 100.0 mL of NaOH added
